摘要
以航天器的编队飞行控制为工程背景,利用PIMCSD工具箱设计了航天器远/近程逼近的时变控制方案,并在飞行控制仿真平台上通过了验证。仿真结果表明,相对于传统的定常控制器方案,新的时变控制器方案可以在更短的控制时间内,以更少的燃料消耗,达到更高的终端控制精度,从而验证了控制方案的可行性、有效性和先进性。同时,提出的时变控制器简化实现方案不仅可以保持良好的性能指标,也便于工程设计和实现。这些工作为航天器编队控制系统的工程设计提供了有益的参考。
Taking formation flying control of spacecrafts for engineering background, with the aid of PIMCSD toolbox, a new time-varying controlling scheme is designed for far/short-range approaching of spacecrafts, and has been validated on a simulation platform of spacecraft flight control. Simulation results demonstrate that, comparing with traditional time-invariant controller, the new scheme of time-varying control- ler achieves a higher terminal control precision within a shorter time-interval and with less fuel consumption, so its feasibility, effectiveness and advancement are proved. Furthermore, the simplified implementation strategy of time-varying controller proposed makes the project design and execution easier while keeps almost the same good performances as the original one have. The new scheme provides a useful reference to project design of spacecrafts formation flying control.
